Alto Douro – Serra de Sampaio, Portugal wind farm facts and numbers

Alto Douro – Serra de Sampaio wind project was installed in Viseu, Portugal It was completed in 2012 and is owned by .

It is near Sampaio.

See below for data.

For the most part, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or more.

The very best location for something such as Alto Douro – Serra de Sampaio would be a steady availability of non-turbulent wind. Additionally, you wouldn’t get a turbine like involved if Alto Douro – Serra de Sampaio was not built near local demand or transmission capaSampaio.

Before construction, Alto Douro – Serra de Sampaio was probably screened on the foundation of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not enough for accurate siting of a large wind power project.

Collection of site-specific data for wind speed and direction would have been essential to determining site potential as a way to finance the project. Winds around Sampaio are examined for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.

Altitude would also have a part to playwithin a project like Alto Douro – Serra de Sampaio. This is because of drag The rise in velocity with altitude is most spectacular near the surface and is affected by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity increases with altitude and is also more obvious near land and is changed by landscape, surface and obstructions.

Wind speeds raising with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, raises the anticipated wind speeds by 10%, and the predicted power by 34%.

The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect one another. But this might not be the way it is in hilly areas.

At a substation, it medium-voltage electric energy is improved in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and perhaps roads to each and every turbine site.
